negotiate

Hi, I am looking for Home Loan from Westpac (to get staff benefits). Though they give decent discount to every employee, they mentioned that the discount is reasonable and no further discount could be given. Effectively, it is 7.06% variable rate. Now, does anyone know if the Bank...

I am a first home buyer. How do I determine whether I should go for a fixed or variable rate? What are the things to remember? Also, is it a common practice to negotiate a rate (either fixed or variable) with the bank? If yes, can I still negotiate a rate after I have been pre-approved?
